SEAL-LOCK.

Patented Dec. 4, 1906.

To aZZ whom it may concern.-

Be it known that I, THEODORE EDDY VAN DERWERKEN, a citizen of the UnitedStates, and a resident of Green Island, in the county otAlbany and Stateof New York, have invented a new and Improved Seal-Lock, of which thefollowing is a full, clear, and exact description.

My invention relates to a lock for cars and for other purposes, theprincipal objects being to provide means whereby a destructible seal canbe applied to the lock in such a manner that the opening of the lockwill cause the destruction of the seal, to provide means also wherebythe car can be locked with an ordinary wired seal either when the sealswhich are intended to go with the lock are absent or even when the dooris not fully closed, also to provide simple and effective means forholding the seal, for destroying it, and in general simplifying andimproving locks of this character.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of a portion of i the car, showing a lockconstructed in accordance with the principles of my invention appliedthereto. Fig. 2 is an elevation on an enlarged scale, showing the lockin closed position with the seal in place. Fig. 3 is a similar viewshowing the door and lock open and the seal destroyed. Fig. 4 is asectional view on the line t 4 of Fig. 2. Fig. 5 is a sectional view onthe line 5 5 of Fig. 2. Fig. 6 is a rear elevation of the movable partof the lock, and Fig. 7 is a plan of the seal which I prefer to employ.

On one portion of the device to be locked, preferably on the movableportion or the door, I locate in a fixed position a plate 10, the plate10 having an undercut recess 11 on its upper side and a flat surfaceextending over the main portion of the plate and bounded by a ledge 12.The outer side 13 of this ledge is curved to correspond with the curvededge 14 of a pivoted latch 15, which constitutes the second part of thelock and is preferably pivoted on the frame or other stationary part ofthe structure to which the lock is to be applied. The latch is providedwith a projection 16, which when the parts are locked g her fit int theunderc t depression 11, as is indicated in 131g. latch is preferablypivoted on a bracket 17, which is provided with perforations 1 8, andthe end of the plate is also provided with a perforation 19. Thesepertorationsconstitute means whereby the wire of ordinary seal can beemployed to seal the car when the door is not entirely closed or whenthe seal which I further employ is not at hand. The plate 10 is providedwith a depression for the reception of a seal 21. I prefer to constructthis seal in the simple form of a thin sheet of lead or otherreadilydestructible metal or the like. Through the depression 20 runs aslot 22, in which is located a slide 28. This slide has a projection 24extending upwardly through the slot and provided with a rounded edge 25on its top. Immediately below said edge is a sharp edge 26, constitutinga cutting-blade. This slide rests upon a plate 27, which is fitted inthe bottom of the plate 10 and extends to the upper edge thereof. Theplate has a flange 28 fitting in a socket in the plate 10 to assist inholding it in position. The plate 10 is provided with a pair of clips29, which extend inwardly from the surface of the depression 20 and holdthe seal in position under normal conditions.

The operation of the cutting-blade on the slide 23 is caused by aresilient-arm 30 on the rear of the latch. This arm is fixed to thelatch at one end, and the latch is provided with a depression 31 at theother end to permit the arm to spring inwardly during its passage by theprojection 24. This depression extends beyond the end of the latch,which is slightly slanted and permits the operation which will now bedescribed.

In order to seal the look, a sheet-metal or other seal is placed in thedepression 20, the slide being at the lower edge thereof. When the dooris closed, the latch is brought around on its pivot into the surfacelocated between the two parts of the ledge, and in entering it will beseen that the arm 30 passes over the seal until it comes into engagementwith the surface 25 of the cutter. The further movement of the latchcauses the arm 30 to be forced inwardly until it passes over the rearedge of the cutter. The opening of the latch will then cause the cutterto move out along the slot in which it is located, so as totear theseal. As the latch moves upward the resilient arm 30 assumes an inclinedposition with respect to the projection 24, and when the cutter reachesthe end of its stroke the projection is at the end of the resilient arm30 and slips over, as clearly shown in dotted lines in Fig. 2.

. In order to provide further means for sealing the parts together whenthey are in closed position, I have provided a pair of lugs 32, one onthe latch and one on the plate 10, each of these lugs having aperforation 33. The wire of the seal can be put through theseperforations and the car sealed in a manner similar tothe usual one.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1 1. A seal-lock comprising a plate having adepression for a seal and a slot extending across said depression, acutting-blade located in said slot, and a latch having means foroperating said cutting-blade.

2. A seal-lock comprisin a plate having a depression for a destructib eseal, a slot extending across said depression, a slide located in saidslot and having a cutting edge, and a latch having means for operatingsaid outting edge when the latch is moved away from said plate.

3. A seal-lock comprising a plate having a depression for receiving adestructible seal, and a slot extending across said depression, a slidelocated below said slotand having a projection provided with a cuttingedge extending into the said depression, said projection having a curvedupper surface, a latch for engaging the plate and provided with aresilient arm adapted to move over said curved surface and engagebeneath the projection when the latch is engaged with the plate wherebyto move the slide when the latch is disengaged from the plate.

4. A seal-lock comprising a plate having means for supporting adestructible seal and provided with a ledge on one side thereof, abracket, a latch pivoted to said bracket and adapted to fit within thesaid ledge, and a pair of perforated lugs, one on the latch and theother on the ledge.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
